of Ringwood Manor, county of Passaic,

State of'New Jersey, have invented certain new and useful Improvements in Vapor Electric Lamps and Connections, of which the following is a specification.

The present invention relates to an elec-" trical apparatus in which a suitable gas or vapor inclosed in a transparent container is made luminous by the passage of electric current.

The type of apparatus illustrated is adapted for various uses, and the novel features of the said device will be explained in the specification and llhe illustrations, Figures 1 and 2, show similar types of electrical apparatus of this sort, the main difference appearing in the electrical connections for the lamp.

The container consists of a tube, 1, of glass or other transparent material, pro-' vided with electrodes, 2, 3 and 4. The electrode 2 is here shown as a body of solid conducting material such as iron, while the elecat the top serving as a cooling or condens- .ingchamberwhereby the vapors formed in the operation of the'lamp are condensed and the general capacity of the device for radiating heat is increased.

In Fig. 1, the electrodes 2 and 3 are connected with the positive side of an electric circuit and the electrode 4 with the negative side. InFig. 2, the electrode 2 is positive and the electrodes 3 and 4 are negative.

I may interpose suitable resistances or inductance devices}? and 8, in the wires leading to the, electrodes, as may be desired or required for different uses of the apparatus and for steadyin the operation thereof.

In the lamp lllustrated in Fig. 2, it is a di erent set of connections for the elec= fully set forth in the 'cation filed March 19, 1903, Serial Number found that the vapor in the lower part of the lamp is denser than in the upper part, the quantity of current passing through the said lower half being approximately double that passing through the upper half. 'The apparatus may be used in testing the operations which take place. in an inclosed gas or vapor carrying electric current, :or it may be utilized for producing different effects in different parts of a single inclosing cham- Fi 2 is made use of simply to illustrate trodes, and it will be understood that these connections may be still fu'rther varied to suit different requirements,- at the will of.

the operator.

In operating thls lamp the mercury which 70 is condensed in the chamber 6 is redistributed for condensation, passing down the tube into the pocket 5 and overflowing from that pocket into the lower part of the tube and there re-constructing the electrode 4. This is found to be a valuable feature of. the lamp and is one ofthe features constituting the present invention.
